TLDR: Make sure to keep your options open even if you make it to the final stage of interviews. They could always fill the spot with an internal person. I got to the point where I did a full day of interviews with an executive, several people from different teams, and lunch with the hiring manager. Everyone was very nice and professional and even after speaking with the executive, they offered to answer any of my questions post-interview, which sounded promising. Ultimately they went with an internal person. Just keep your feet on the ground while interviewing even if they make it seem like you're a shoe-in. It was an insightful process but keep in mind they always have someone in the wings. This is great news if you're already in there but not so great when you're trying to get in. Keep in mind the whole process (including constant back and forth/rescheduling with the recruiter) was about 10-12 weeks. Do not hold your breath but enjoy the process if the opportunity presents itself.
